A setup tool that turns a project or study folder into a tracked learning environment. It configures tutoring rules, creates an education database, and collects or updates the student profile.

In plain words
What is it for?
Use it when starting a new educational project or study folder. It sets up project instructions, global records, and project-local learning tracking.
Why use it?
It gives study sessions a consistent teaching setup and remembers the student’s goals, level, interests, and progress. This allows later learning plans and reviews to be tailored.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

init-edu scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Initialize Educational Environment

Before accessing education data, read ${CLAUDE_PLUGIN_ROOT}/references/education-data.md. Resolve <education-db> using that contract. Current session ID: ${CLAUDE_SESSION_ID}.

1. Inspect before changing files

Read the project CLAUDE.md, .claude/CLAUDE.md, .claude/settings.json, .claude/claude-teacher.json, and existing <education-db>/student.json and dashboard.json, when present.

  • Preserve all unrelated instructions, settings, hooks, and student work. If a JSON file is invalid, report it and recover it before updating.
  • Do not write setup files until the student has supplied the required onboarding and project answers. Honor supplied answers; do not ask again.
  • If a profile exists, greet the student and ask whether to set up this project using it or update selected profile fields. Never delete the profile to edit it.
  • If they want a full reset, direct them to /claude-teacher:reset-edu. Do not invoke or reproduce that manual-only skill automatically.

2. Onboard a new student

Ask one question at a time and wait for the answer. The student may skip personal questions; save unknown values as null or empty arrays. Do not require an age or infer one.

  1. What should I call you?
  2. How old are you, or would you prefer to skip that?
  3. What is your current level: beginner, some experience, intermediate, or advanced?
  4. What subjects or skills do you already know well?
  5. Which learning approaches do you prefer: diagrams, examples first, analogies, theory first, hands-on practice, or a mix?
  6. What frustrates you when learning?
  7. What are your goals and any deadlines?
  8. What interests or hobbies could I use for examples?
  9. How would you describe your ideal teacher's tone and approach?

Save an object in <education-db>/student.json after collecting the answers:

{
  "name": "preferred name",
  "age": null,
  "level": "beginner",
  "known_subjects": [],
  "learning_style": [],
  "frustrations": [],
  "goals": [{"goal": "student's goal", "deadline": null}],
  "interests": [],
  "teacher_persona": "student's own description"
}

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
